You can no longer turn off tabs in 10.4. You used to be able to detach the mTIClientWnd and the documents still appeared maximised and everything was okay. Now you cant.
 
For example in VisualStudio sample comment out following lines in MainFrm.cpp:


 VERIFY(m_MTIClientWnd.Attach(this, TRUE));
 m_MTIClientWnd.EnableToolTips();


 m_MTIClientWnd.GetPaintManager()->m_bShowIcons = FALSE;
 m_MTIClientWnd.SetNewTabPosition(xtpWorkspaceNewTabLeftMost);
 m_MTIClientWnd.SetFlags(xtpWorkspaceHideArrowsAlways | xtpWorkspaceShowActiveFiles);
 
And run it. The docs are in non-maximised state but cant be moved or maximised.

That works a bit better, but if I do this whilst the program is running (i.e. through an Options page) then it doesnt work very nicely at all ... can you give me the steps I should do to achieve this.
 
Currently I 'detach' the MTIClientWnd if its off, and 'attach' it if its on, and I have wrapped up the code on ChildFrm::OnCreate around a check for the tabs enabled flag.
 
What else do i need to do?

void CMainFrame:OnChangeWorkspaceOption()


{
 if( m_bShowTabs )
 {
  VERIFY( m_MTIClientWnd.Attach( this, TRUE ) );
  m_MTIClientWnd.EnableToolTips();
  m_MTIClientWnd.GetPaintManager()->m_bShowIcons = TRUE;
 }
 else
 {
  m_MTIClientWnd.Detach();
 }


}


 


and...



int CChildFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
 if (CMDIChildWnd::OnCreate(lpCreateStruct) == -1)
  return -1;


 if( theApp.GetMainFrame()->m_bShowTabs )
 {
  XTPImageManager()->SetMaskColor( RGB(0xC0, 0xC0, 0xC0) );
  VERIFY( m_wndDocumentViewToolBar.CreateToolBar( WS_TABSTOP|WS_VISIBLE|WS_CHILD|CBRS_TOOLTIPS, this ) );
  VERIFY( m_wndDocumentViewToolBar.LoadToolBar( IDR_SGENIETYPE ) );


  CMenu* pMenu = GetSystemMenu(FALSE);
  pMenu->RemoveMenu(SC_RESTORE, MF_BYCOMMAND);
  pMenu->RemoveMenu(SC_MINIMIZE, MF_BYCOMMAND);
  pMenu->RemoveMenu(SC_MAXIMIZE, MF_BYCOMMAND);
  pMenu->RemoveMenu(SC_MOVE, MF_BYCOMMAND);
  pMenu->RemoveMenu(SC_SIZE, MF_BYCOMMAND);
 }


 return 0;
}

Hi, problem that if you use Enablegroups option (think it was FALSE in previour releases and was reason why it worked) TabClient automatically remove caption if child windows. SO you have switch it back:
 
 
if (m_MTIClientWnd.GetSafeHwnd())
{
m_MTIClientWnd.Detach();

HWND hWnd = ::GetWindow(m_hWndMDIClient, GW_CHILD);
while (hWnd)
{
CWnd::ModifyStyle(hWnd, 0, WS_CAPTION, SWP_FRAMECHANGED);
hWnd = ::GetWindow(hWnd, GW_HWNDNEXT);
}
MDICascade();
}
else
{
HWND hWnd = ::GetWindow(m_hWndMDIClient, GW_CHILD);
while (hWnd)
{
CWnd::ModifyStyle(hWnd, WS_CAPTION, 0, SWP_FRAMECHANGED);
hWnd = ::GetWindow(hWnd, GW_HWNDNEXT);
}
m_MTIClientWnd.Attach(this, TRUE);
}

RecalcLayout();
::RedrawWindow(m_MTIClientWnd, 0, 0, RDW_INVALIDATE|RDW_UPDATENOW|RDW_ALLCHILDREN);
